Im getting this problem when tryin to export 8k footage to 8k exr sequence "The GPU failed to perform image processing because of an error Error code:0."
Do you think its a driver issue (i know its wining about the Gpu). I have not had problem with this prior when working with cineform renders.

I have been pretty happy with my current nvidia drivers but I think I will update them. Do you run the studio drivers?
What drivers and version are you running? I have a 1080 Ti.

Also can you export 8k from a 4k timeline? I tried it and get a warning that all nodes will be rendered at timeline resolution. So i bump upp the timline to 8k prior to render.
